reason to think that, contrary to what many believe, the Founders were
not infallible. I have long been a proponent of parliamentary democracy.
Here's an extract from an article, "It's Going to get Much Worse than a Showdown." http://www.slate.com/articles/business/moneybox/2013/10/juan_linz_dies_yale_political_scientist_explains_why_government_by_crisis.html
"The problem, according to Linz, is right there in the title: too much reliance on presidents. In Linz’s telling, successful democracies are governed by prime ministers who have the support of a majority coalition in parliament. Sometimes, as in the British Commonwealth or Sweden or post-Franco Spain, these prime ministers are formally subordinate to a monarch. Other times, as in Germany or Israel or Ireland, there is a largely ceremonial, nonhereditary president who serves as head of state. But in either case, governing authority vests in a prime minister and a cabinet whose authority derives directly from majority support in parliament.
When such a prime minister loses his parliamentary majority, a crisis ensues. Either the parties in parliament must negotiate a new governing coalition and a new cabinet, or else a new election is held. If necessary, the new election will lead to a new parliament and a new coalition. These parliamentary systems are sometimes very stable (see the United Kingdom or Germany) and sometimes quite chaotic (see Israel or Italy), but in either case, persistent legislative disagreement leads directly to new voting.
In a presidential system, by contrast, the president and the congress are elected separately and yet must govern concurrently. If they disagree, they simply disagree. They can point fingers and wave poll results and stomp their feet and talk about “mandates,” but the fact remains that both parties to the dispute won office fair and square. As Linz wrote in his 1990 paper “The Perils of Presidentialism,” when conflict breaks out in such a system, “there is no democratic principle on the basis of which it can be resolved, and the mechanisms the constitution might provide are likely to prove too complicated and aridly legalistic to be of much force in the eyes of the electorate.” That’s when the military comes out of the barracks, to resolve the conflict on the basis of something—nationalism, security, pure force—other than democracy."
